BN chairperson Ahmad Zahid Hamidi has been urged to focus on component parties within his coalition and not other political partners.
MCA secretary-general Chong Sin Woon said Zahid must be cautious when speaking about cooperation between BN and Pakatan Harapan.
As the BN chairperson, he should look after the interests of BN component parties, not Harapan and especially DAP, he said.
